Einstein's theory of General relativity says that time slows down or speeds up depending on how fast you move relative to something else. ... The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity.

Pretty much, the faster an object moves, the larger that object gets, and generates a larger gravitational force.

The only reason it doesn't really appear larger is because space, time, and light bends around the object due to its gravitational force, making the object appear smaller than it really is as it moves through space, until energy has exhausted and it no longer moves.

This is why, well we don't gravitate towards a parked car, if you run into a parked car, you will not get too badly hurt. But, if you get hit by a car, it will hurt like hell. That's because you are feeling the g force of that object in motion, practically obliterating your body on collision.

In order for an object to move it has to generate a gravitational force equal to or greater than the planets effect to itself, otherwise it would be stuck in place.

Objects like wheels and similar devices work like a centrifuge, in which the weight and pressure contained on the outside pull from the center of the rotation, to stabilize for the g force the object moves in, otherwise the tires would pop!

I want to try something, in theory. If you get a piece of paper and draw a dot on the corner of it, and one in the center, there should be 2 different ways to connect the dot. Now remember, in science, that piece of paper qualifies as a plane in space!

1 is to draw a line connecting it.

2 is to actually fold the paper!

This is how Black Holes are demonstrated in theory...

Do you think we can travel with this knowledge? (Eventually)
